PVC glue on CPVC

A friend of mine started a complete plumbing project at his cabin. He bought all CPVC fittings and pipe and bought PVC glue not realizing till back at the supply house to get more fittings that there is CPVC glue. He is about a 1/3 of the way done. He is asking me if he should rip out what he has finished and start over. He is more concerned about the hot water side. What do you think?

Start over. It will eventually fail. Try and explain to the insurance company when they deny a claim. And due to improper installation, they will deny the claim.

Yep.

Can color? The red can is an all-purpose that is for both, at least the Oatey brand is.
